  • About Our Bauxite
    15-11-2023
    Our country's bauxite reserves are extremely rich. The uses of bauxite are mainly used as raw materials for refractories, grinding materials, due to high-alumina cement. Bauxite is widely used.(1) Aluminum smelting industry. Used in national defense, aviation, automobiles, electrical appliances, che
  • Cenosphere in Refractory Materials
    10-11-2023
    The main chemical components of the cenosphere are oxides of silicon and aluminum, of which silicon dioxide is about 50-65% and aluminum trioxide is about 25-35%. Because the melting point of silicon dioxide is as high as 1725 degrees Celsius, and the melting point of aluminum trioxide is 2050 degre
  • About Bauxite Clinker
    09-11-2023
    Bauxite clinker is a solid material calcined at high temperature in rotary kiln. The main purpose of calcination is to remove crystal water and increase alumina content.The clinker is gray, light yellow and dark gray bauxite clinker. According to specifications, bauxite clinker can be divided into p
  • Refractory Materials for Castables

  • Coatings with High Alumina in Thermal Baffle
    06-11-2023
    The molten iron just entering the furnace is above1250-1350 temperature. The freezing point of molten steel is 1064℃, and the smelting point of steel is 1500℃.The steelmaking furnace is full of smolten steel. Why won't it be melted too just like the steel? The reason is that the coatings containing
  • Why Choose High Alumina Refractory Materials for Firebricks?
    06-11-2023
    The reason why high-alumina raw materials is selected to produce refractory bricks is that its high resistance to temperature increases with the elevation of Al2O3 content.With the decrease of impurity content in raw materials, fire resistance is improved. At the same time, if the aluminum content o
